General description

Acetaldehyde-2,4-DNPH can be obtained as an oxidation product of the reaction between alpha-pinene with hydroxyl radicals, which is monitored by gas chromatography, high performance liquid chromatography and detected by using mass spectral analysis.

Application

Acetaldehyde-2,4-DNPH has been used as an internal standard to study the ozonation of an antidepressant fluoxetine (FX) and its principle metabolite product norfluoxetine (NFX) using kinetic method of analysis and high performance liquid chromatography coupled with mass spectrometry.
